在本申请实施例中，当第一电子设备与该保护壳物理连接后，第一电子设备可以通过该保护壳向第二电子设备进行无线电能传输。具体的，保护壳可以内置有物理接口，第一电子设备的充电接口与保护壳的物理接口进行物理连接后，即可使得第一电子设备与保护壳之间实现物理连接，并且，第一电子设备输出的电能可以通过该物理接口被保护壳所接收到；同时，保护壳还内置有处理器，在保护壳接收到第一电子设备传输的电能时，向同样内置于保护壳中的无线电能收发器发送无线发射指令，这样，无线电能收发器在响应该无线发射指令后，可以根据保护壳接收到的电能向第二电子设备进行无线电能传输。由此 可见，即使第一电子设备不具有为其它电子设备进行无线充电功能，也即，第一电子设备上不具有实现无线充电功能的发射端功能，第一电子设备在与保护壳物理连接后，第一电子设备的电能也可以传输至保护壳中，并由保护壳中的无线电能收发器向第二电子设备进行无线电能传输，从而使得不具有为其它电子设备进行无线充电功能的第一电子设备也能为第二电子设备补充电量或者提供电量，进而使得第二电子设备在存在充电需求时可以由第一电子设备为其实现电量补充。
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请中记载的一些实施例，对于本领域普通技术人员来讲，还可以根据这些附图获得其他的附图。
图1为本申请实施例中一示例性应用场景示意图；
图2为本申请实施例中一种用于无线电能传输的保护壳以及第一电子设备的结构示意图；
图3为本申请实施例中手机与保护壳之间的连接示意图；
图4为本申请实施例中一种无线电能传输的方法流程示意图；
图5为本申请实施例中一种用于无线电能传输的系统结构示意图。
目前，无线电能传输技术虽然得到推广应用，但是并非所有的电子设备相互之间均可以进行无线充电，即存在部分电子设备(为便于描述，以下称之为第一电子设备)不具有给其它电子设备(为便于描述，以下称之为第二电子设备)进行无线充电的功能，这使得当第二电子设备存在充电需求时，不具有为其它电子设备进行无线充电功能的第一电子设备无法为第二电子设备进行无线充电，从而使得第二电子设备在急需充电但是又没有充电器可用的情况下难以获得电量补充。
基于此，在本申请实施例提供了一种用于无线电能传输的保护壳，当第一电子设备与该保护壳物理连接后，第一电子设备可以通过该保护壳对第二电子设备进行充电。具体的，保护壳可以内置有物理接口，第一电子设备的充电接口与保护壳的物理接口进行物理连接后，即可使得第一电子设备与保护壳之间实现物理连接，并且，第一电子设备输出的电能可以通过该物理接口被保护壳所接收到；同时，保护壳还内置有处理器，在保护壳接收到第一电子设备传输的电能时，向同样内置于保护壳中的无线电能收发器发送无线发射指令，这样，无线电能收发器在响应该无线发射指令后，可以根据保护壳接收到的电能向第二电子设备进行无线电能传输。由此可见，即使第一电子设备不具有为其它电子设备进行无线充电功能，但是，第一电子设备在与保护壳物理连接后，第一电子设备的电能可以传输至保护壳中，并由保护壳中的无线电能收发器根据该电能向第二电子设备进行无线电能 传输，从而使得不具有为其它电子设备进行无线充电功能的第一电子设备也能为第二电子设备提供或者补充电量，进而使得第二电子设备在存在充电需求时可以由第一电子设备为其实现电量补充。
需要说明的是，两个均具有为其它电子设备进行无线充电功能的电子设备之间也可以利用保护壳实现无线电能传输，即，利用保护壳对第二电子设备进行充电的电子设备，除了可以是上述不具有为其它电子设备进行无线充电功能的电子设备以外，也可以是具有为其它电子设备进行无线充电功能的电子设备。进一步的，当第一电子设备具有为其它电子设备进行无线充电功能时，若该第一电子设备与保护壳连接后，该第一电子设备原先的无线充电功能可以出现暂时性异常或者失效，并利用保护壳为第二电子设备进行无线充电。
作为一种示例，本申请实施例可以应用于如图1所示的示例性应用场景。在该场景中，上述第一电子设备具体可以是如图1所示的手机101，该手机101可以不具有为其它电子设备进行无线充电功能，上述第二电子设备具体可以是如图1所示的蓝牙耳机103，当手机101需要对蓝牙耳机103进行充电时，手机101可以与保护壳102进行物理连接，具体可以是将手机101的充电接口与保护壳102的物理接口进行物理连接，在成功建立物理连接后，手机101可以通过该物理连接向保护壳102传输电能，并且在保护壳102接收到该电能时，保护壳102中的处理器可以向内置在保护壳102中的无线电能收发器发送无线发射指令，以便无线电能收发器响应接收到的无线发射指令，根据保护壳102所接收到的电能对蓝牙耳机103进行无线充电，从而使得不具有无线充电功能的手机101也可以对蓝牙耳机103进行电量补充。
可以理解的是，上述场景仅是本申请实施例提供的一个场景示例，本申请实施例并不限于此场景。比如，本申请实施例中的第二电子设备除了可以是蓝牙耳机103以外，也可以是手机等其它具有无线充电功能的电子设备等。总之，本申请实施例可以适用于任何可适用的场景中，不限于上述场景示例。
为使本申请的上述目的、特征和优点能够更加明显易懂，下面将结合附图对本申请实施例中的各种非限定性实施方式进行示例性说明。显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
参阅图2，图2示出了本申请实施例中一种用于无线电能传输的保护壳以及第一电子设备的结构示意图。如图2所述，第一电子设备可以包括处理器、电池单元以及充电接口；保护壳可以内置有物理接口、无线电能收发器和处理器。
当第一电子设备利用保护壳向第二电子设备进行无线电能传输时，第一电子设备与保护壳之间可以先建立物理连接，具体可以是将第一电子设备中的充电接口与保护壳中的物理接口进行物理连接。在一些可能的实施方式中，第一电子设备的充电接口与保护壳的物理接口均可以是通用串行总线(universal serial bus，USB)接口，则可以利用USB数据线将第一电子设备的USB接口与保护壳的USB接口建立连接，从而使得第一电子设备与保护壳建立物理连接。
实际应用中，在第一电子设备与保护壳建立物理连接后，第一电子设备中的电池单元可以通过该物理链路对保护壳进行供电。具体的，第一电子设备中的电池单元可以在充电接口上输出电能，以使得电能经第一电子设备中的充电接口与保护壳的物理接口之间的物理链路可以被传输至保护壳，这样，保护壳可以将该电能传递至第二电子设备，从而实现对第二电子设备的无线充电。实际应用中，第一电子设备中的电池单元具体可以包括电池以及相关的电路等。
在进一步的实施方式中，在第一电子设备的充电接口物理连接到保护壳的物理接口后，第一电子设备可以主动或者被动获取到保护壳的设备信息。具体的，若第一电子设备主动获取保护壳的设备信息，则第一电子设备中的处理器可以在充电接口物理连接到保护壳的物理接口后，向保护壳发送探测指令信息；保护壳在接收到该探测指令信息后，该保护壳内的处理器可以响应于该探测指令信息，获取自身的设备信息，并将该设备信息发送给第一电子设备。
其中，第一电子设备与保护壳之间可以是通过有线传输探测指令信息，比如，第一电子设备可以是通过USB数据线将该放电指令信息传输至保护壳等，并遵循功率输出(Power Delivery，PD)协议进行数据交互，具体可以是遵循USB1.0、USB2.0、USB3.0及以上等协议进行数据交互。当然，在其它可能的实施方式中，第一电子设备与保护壳之间也可以是通过无线传输探测指令信息，比如，保护壳内部可以配置有蓝牙通信模块，这样，第一电子设备可以与保护壳内的蓝牙模块建立蓝牙连接，并通过蓝牙将该探测指令信息传输至保护壳等。
类似的，针对于保护壳的设备信息，既可以是通过有线的方式由保护壳传输至第一电子设备，比如，保护壳可以是通过USB数据线将该设备信息传输至第一电子设备等；当然，保护壳与第一电子设备之间也可以建立无线连接，然后，保护壳可以将自身的设备信息由该无线连接传输至第一电子设备，比如，保护壳与第一电子设备建立蓝牙连接后，可以通过蓝牙将该设备信息发送给第一电子设备。
除了可以是由第一电子设备主动获取保护壳的设备信息以外，在其它可能的实施方式中，也可以是由保护壳主动将自身的设备信息发送给第一电子设备，以使得第一电子设备被动获得该设备信息。具体实现时，在第一电子设备的充电接口与保护壳的物理接口完成物理连接后，保护壳中的处理器可以获取自身的设备信息，并主动将该设备信息发送给第一电子设备。
其中，保护壳在主动向第一电子设备传输设备信息时，可以是通过有线的方式进行传输，也可以是通过无线的方式进行传输，具体传输方式在此并不进行限定。
值得注意的是具体实现时，用户可以在第一电子设备上执行为第二电子设备进行充电的触发操作，例如，用户可以在第一电子设备的触摸显示屏上点击“确认”控件以确认利用保护壳对其它的电子设备进行无线充电，则第一电子设备可以响应于该触发操作，由该第一电子设备中的处理器生成放电指令信息，并将该放电指令信息发送给保护壳，以利用该放电指令信息指示保护壳利用接收到的电能对第二电子设备进行无线充电。
其中，第一电子设备与保护壳之间，可以是通过有线传输该放电指令信息，例如，第 一电子设备可以是通过USB数据线将该放电指令信息传输至保护壳等。当然，在其它实施方式中，第一电子设备与保护壳之间，也可以是通过无线传输该放电指令信息，比如，第一电子设备可以通过蓝牙将该放电指令信息传输至保护壳等。
保护壳在接收到第一电子设备发送的放电指令信息后，保护壳中的处理器可以响应该放电指令信息，生成用于指示无线电能收发器进行无线充电的无线发射指令，并将该无线发射指令发送给无线电能收发器。这样，保护壳中的无线电能收发器可以响应接收到的无线发射指令，根据接收到的电能向第二电子设备进行无线电能传输。
需要说明的是，上述实施方式中，保护壳是基于第一电子设备发送的放电指令信息确定需要对第二电子设备进行无线充电，在其它可能的实施方式中，当保护壳的物理接口与第一电子设备的充电接口建立物理连接时，第一电子设备中的电池单元可以基于该充电接口向保护壳输出电能，而保护壳在接收到该电能后，可以直接根据该电能向第二电子设备进行无线电能传输，从而无需第一电子设备的指示与授权。
需要说明的是，当第一电子设备不具有为其它电子设备进行无线充电功能时，第一电子设备可以通过与其存在物理连接的保护壳实现对其它电子设备的电量补充，从而使得不具有为其它电子设备进行无线充电功能的第一电子设备也能为第二电子设备进行无线充电，进而使得第二电子设备在存在充电需求时可以由第一电子设备为其实现电量补充。但是，这并不限定本实施例中的第一电子设备只能是不具有无线充电功能的电子设备，在其它的应用场景中，该第一电子设备也可以是具有为其它电子设备进行无线充电功能的电子设备，并且也可以利用保护壳向第二电子设备进行无线电能传输。比如，在一些可能的应用场景中，当第一电子设备需要对两个电子设备进行充电时，第一电子设备可以利用本身所具有的为其它电子设备进行的无线充电功能对其中一个电子设备进行无线充电，同时，第一电子设备通过与保护壳连接后，利用该保护壳可以对另一个电子设备进行无线充电，从而使得该第一电子设备可以同时对两个电子设备提供电量补充。或者，第一电子设备与保护壳之间建立物理连接后，第一电子设备中为其它电子设备进行无线电能传输的相关功能可以暂时性失效，并利用保护壳实现对其它电子设备的电量补充。
值得注意的是，上述实施例中，第一电子设备是利用保护壳对其它电子设备进行电能传输，以为其它电子设备提供电或者量补充电量，而在另一些可能的实施方式中，其它设备也可以利用该保护壳对第一电子设备进行无线电能传输，以为该第一电子设备提供电量或者补充电量。为方便描述，第一电子设备利用保护壳为其它电子设备进行无线电能传输时输出的电能，称之为第一电能，其它电子设备利用保护壳为第一电子设备进行无线电能传输时提供的电能称之为第二电能。
则当存在第三电子设备对第一电子设备进行充电或者供电时，保护壳中的无线电能收发器可以在第三电子设备向保护壳无线充电时生成第二电能。值得注意的是，由于保护壳所生成的第二电能的电压可能不满足第一电子设备充电时所要求的电压，因此，无线电能收发器在生成第二电能后，可以向调压器发送第二电能，以便利用调压器调整对第一电子设备进行无线电能传输时的第二电能的电压。
其中，对于第一电子设备进行无线充电时第二电能所需满足的电压，保护壳可以从第一电子设备处获得。具体实现时，第一电子设备可以向保护壳中的处理器发送电压调节信息，并按照电压调节信息向调压器发送电压调节指令，该电压调节指令指示了对第一电子设备进行充电时所需满足的电压。
这样，保护壳中的调压器可以按照接收到的电压调节指令所指示的电压，向保护壳的物理接口输出该第二电能，以使得该第二电能在物理接口输出时的电压满足第一电子设备的充电电压需求。
为了便于理解本申请实施例的技术方案，下面对结合图3对本申请实施例进行举例说明。在图3所述的技术方案中，上述第一电子设备具体可以是手机，上述的保护壳即为手机的保护壳，手机的USB接口与保护壳的USB接口之间可以进行物理连接。
在本实施例中，当用户需要利用手机对其它电子设备进行充电时，用户可以将手机与保护壳上的USB接口通过USB数据线实现物理连接；然后，手机检测到手机与保护壳之间存在物理连接，触发手机上的电池单元在USB接口上输出电能，并由手机与保护壳之间的USB数据线将该电能传输至保护壳中，以对保护壳中的电路进行上电，使得保护壳中的各部件上电运行；并且，处理器可以生成探测指令信息，并通过手机中的通信模块将该探测指令信息发送给保护壳，由保护壳中的通信模块接收该探测指令信息。
其中，该探测指令信息在手机中的通信模块与保护壳中的通信模块之间，可以采用无线通信(如蓝牙等)的方式进行传输，也可以采用有线通信(如USB数据线等)的方式进行传输。
保护壳中的通信模块在接收到该探测指令信息后，可以将其发送给保护壳中的处理器，以便于该处理器响应该探测指令信息，获取自身的设备信息，并将该设备信息通过通信模块发送给手机。
其中，该探测指令信息在手机中的通信模块与保护壳中的通信模块之间，可以采用无线通信的方式进行传输，也可以采用有线通信的方式进行传输。
当然，也可以是由保护壳在检测到与手机通过USB接口实现物理连接后，主动向手机发送自身的设备信息。其中，发送自身的设备信息的方式，既可以是通过有线传输的方式发送，也可以是通过无线传输的方式发送。
在手机的处理器基于所接收到的设备信息确定保护壳为合法设备后，手机的触摸显示屏上可以显示有内容为“请确认是否利用保护壳对其它电子设备进行充电”的提示框，并呈现“确认”以及“取消”两个控件。用户可以在该手机上执行点击“确认”控件的操作，以通知手机确认需要对其它电子设备进行充电。则，手机上的处理器可以响应该触发操作，生成放电指令信息并向保护壳发送该放电指令信息，以指示保护壳根据该放电指令信息对其它电子设备进行充电。
保护壳中的通信模块在接收到该放电指令信息后，将该放电指令信息发送给保护壳中的处理器，由该处理器响应该放电指令信息，生成无线发射指令并将该无线发射指令发送给无线电能收发器。
保护壳中的无线电能收发器接收到该发电指令信息后，利用手机所提供的电能对其它电子设备进行无线充电，以补充其它电子的设备的电量。
上述过程中是手机利用保护壳对其它电子设备进行充电，而当手机的电量较低或者存在补充电量的需求时，其它电子设备可以利用该保护壳对手机进行电量补充。
具体实现时，其它电子设备可以对保护壳进行无线充电，由保护壳据此生成对手机进行充电的电能。同时，手机还可以向保护壳提供电压调节信息，以告知保护壳对手机进行充电时电能所需满足的电压。
当然，该电压调节信息，可以是通过有线或者无线的方式由手机中的通信模块传输至保护壳中的通信模块。
保护壳中的处理器从通信模块处获得该电压调节信息后，生成相应的电压调节指令，并将该电压调节指令发送给调压器，以便于调压器按照电压调节指令所指示的电压，向USB接口输出相应电压大小的电能，从而实现对手机电量的补充。
此外，本申请实施例还提供了一种用于无线电能传输的方法。参阅图4，图4示出了本申请实施例中一种无线电能传输的方法流程示意图，该方法可以应用于保护壳，并且，该保护壳可以内置有物理接口、无线电能收发器和处理器，该方法具体可以包括：
S401：保护壳通过物理接口接收第一电子设备输出的第一电能。
本实施例中，当第一电子设备需要对第二电子设备进行无线电能传输时，可以先将第一电子设备的充电接口与保护壳中的物理接口进行物理连接，以便第一电子设备所输出的第一电能可以通过该物联连接传输至保护壳中。
实际应用中，第一电子设备在与保护壳建立物理连接后，通常第一电子设备需要获知当前所连接的设备的相关信息。基于此，在一些可能的实施方式中，在保护壳与第一电子设备之间建立物理连接后，第一电子设备可以通过有线或者无线传输方式向保护壳发送探测指令信息，以主动获取保护壳的设备信息；相应的，保护壳可以接收并响应该探测指令信息，获取自身的设备信息，并将该设备信息发送给第一电子设备。当然，在其它可能的实施方式中，保护壳在确定与第一电子设备之间建立物理连接后，也可以主动将预先存储的自身的设备信息发送给第一电子设备，从而无需第一电子设备通过发送探测指令消息的方式来获取保护壳的设备信息，进而可以减少第一电子设备获取保护壳的设备信息时与保护壳之间所需执行的信令交互次数。
其中，保护壳的设备信息在第一电子设备在与保护壳之间进行传输时，可以是通过有线传输方式进行传输，如通过USB数据线进行传输等，也可以是通过无线传输方式进行传输，如通过蓝牙进行传输等，在此不做限定。
S402：保护壳通过无线电能收发器根据第一电能向第二电子设备进行无线电能传输。
本实施例中，保护壳可以是利用内置的无线电能收发器将接收到的第一电能传输至第二电子设备(也即为第一电子设备需要为其进行供电或者充电的电子设备)，因此，保护壳中的处理器可以在确定接收到第一电能后，向无线电能收发器发送无线发射指令，以指示无线电能收发器向第二电子设备传输电能。
在一种示例性的具体实施方式中，保护壳向第二电子设备的电能传输过程可以受第一电子设备的控制，即第一电子设备可以通过有线或者无线传输方式向保护壳发送放电指令信息，以指示保护壳进行无线电能传输。这样，保护壳中的处理器可以接收并响应该放电指令信息，并生成用于指示无线电能收发器进行无线充电的无线发射指令，并将该无线发射指令发送给无线电能收发器。其中，该放电指令信息可以是通过有线或者无线传输方式由第一电子设备传输至保护壳。
当然，在其它可能的实施方式中，保护壳在接收到第一电子设备输出的第一电能后，也可以直接生成无线发射指令，并将该无线发射指令发送给无线电能收发器，以触发对第二电子设备的电能传输，从而无需第一电子设备的指示与授权。
本实施例中，可以在保护壳中配置无线电能收发器，该无线电能收发器可以接收电能，同时也可以发送电能。基于此，无线电能收发器在接收到无线发射指令后，可以根据接收到的第一电能对第二电子设备进行无线电能传输，以利用传输的电能对第二电子设备进行供电或者充电。
当然，当存在第三电子设备对第一电子设备进行充电或者供电时，保护壳中的无线电能收发器可以在第三电子设备向保护壳无线充电时生成第二电能，并利用该第二电能对第一电子设备进行供电或者充电。值得注意的是，由于保护壳所生成的第二电能的电压可能不满足第一电子设备充电时所要求的电压，因此，无线电能收发器在生成第二电能后，可以向调压器发送第二电能，以便利用调压器调整对第一电子设备进行无线电能传输时的第二电能的电压。其中，对于第一电子设备进行无线充电时第二电能所需满足的电压，保护壳可以从第一电子设备处获得。具体实现时，第一电子设备可以向保护壳中的处理器发送电压调节信息，并按照电压调节信息向调压器发送电压调节指令，该电压调节指令指示了对第一电子设备进行充电时所需满足的电压。这样，保护壳中的调压器可以按照接收到的电压调节指令所指示的电压，向保护壳的物理接口输出该第二电能，以使得该第二电能在物理接口输出时的电压满足第一电子设备的充电电压需求。
此外，本申请实施例还提供了一种用于无线电能传输的系统。参阅图5，图5示出了本申请实施例中一种用于无线电能传输的系统，该系统500具体可以包括：保护壳501以及第一电子设备502，其中，保护壳501包括物理接口5011以及无线电能收发器5012。
所述保护壳501，用于通过所述物理接口5011与所述第一电子设备502的充电接口进行物理连接，通过所述物理接口5011接收所述第一电子设备502输出的第一电能；在所述保护壳501通过所述物理接口5011接收到所述第一电能时，向所述无线电能收发器5012发送无线发射指令，以使得所述无线电能收发器5012响应于所述无线发射指令，根据所述第一电能向第二电子设备进行无线电能传输。
所述第一电子设备502，用于通过充电接口与所述保护壳501的物理接口5011进行物理连接，并通过所述充电接口向所述第一电子设备502输出所述第一电能。
在一些可能的实施方式中，所述保护壳501，具体用于：接收所述第一电子设备502发送的放电指令信息；响应于所述放电指令信息，向所述无线电能收发器5012发送所述 无线发射指令。
在一些可能的实施方式中，所述保护壳501，还用于：在所述物理接口5011物理连接到所述充电接口之后，接收所述第一电子设备502发送的探测指令信息；响应于所述探测指令信息，向所述第一电子设备502发送所述保护壳501的设备信息。
在一些可能的实施方式中，所述保护壳501，还用于：在所述物理接口5011物理连接到所述充电接口之后，主动向所述第一电子设备502发送所述保护壳501的设备信息。
在一些可能的实施方式中，所述保护壳501与所述第一电子设备502通过有线传输放电指令信息，或，所述保护壳501与所述第一电子设备502通过无线传输放电指令信息。
在一些可能的实施方式中，所述保护壳501与所述第一电子设备502通过有线传输探测指令信息，或，所述保护壳501与所述第一电子设备502通过无线传输探测指令信息。
在一些可能的实施方式中，所述保护壳501与所述第一电子设备502通过有线传输保护壳501的设备信息，或，所述保护壳501与所述第一电子设备502通过无线传输保护壳501的设备信息。
在一些可能的实施方式中，所述保护壳501还内置有调压器，所述保护壳501，还用于：在第三电子设备向所述保护壳501无线充电时生成第二电能，利用所述无线电能收发器5012向所述调压器发送所述第二电能；接收所述第一电子设备502发送的电压调节信息，按照所述电压调节信息向所述调压器发送电压调节指令，以使得所述调压器按照所述电压调节指令所指示的电压，向所述物理接口5011输出所述第二电能。

本实施例中，即使第一电子设备502不具有为其它电子设备进行无线充电功能，第一电子设备502在与保护壳501物理连接后，第一电子设备502的电能也可以传输至保护壳501中，并由保护壳501中的无线电能收发器5012向第二电子设备进行无线电能传输，从而使得不具有为其它电子设备进行无线充电功能的第一电子设备502也能为第二电子设备补充电量或者提供电量，进而使得第二电子设备在存在充电需求时可以由第一电子设备502为其实现电量补充。
